foreman安装使用

1.centos7支持的最高版本为3.3版本

需要使用>= 6.0.0 < 8.0.0版本的puppet

官网地址为：https://theforeman.org/manuals/3.3/quickstart_guide.html

如果之前安装了puppet8-release需要先卸载rpm -e puppet8-release

#Repositories
#Note: The RPM packages are not tested on Scientific Linux or Oracle Linux. The Foreman installation on Scientific Linux or Oracle Linux may or may not work.

#Enable Puppet's 7.x repository:

sudo yum -y install https://yum.puppet.com/puppet7-release-el-7.noarch.rpm
#Enable the EPEL (Extra Packages for Enterprise Linux), Foreman and SCL (Software Collections) repositories:

sudo yum-config-manager --enable extras #如果报错-bash: yum-config-manager: command not found 则先安装yum install yum-utils
sudo yum -y install epel-release centos-release-scl-rh
sudo yum -y install https://yum.theforeman.org/releases/3.3/el7/x86_64/foreman-release.rpm
#Downloading the installer
sudo yum -y install foreman-installer

使用上面官网的步骤不能安装tfm-rubygem，需要手动添加epel及CentOS-SCLo-scl-rh源

此时直接安装foreman会报错

If 'hostname -f' still returns an unexpected result, check /etc/hosts and put
the hostname entry in the correct order, for example:

  1.2.3.4 hostname.example.com hostname

需要添加hosts解析，而且必须按照这种格式进行填写,不能只写ip和解析要写三个元素，如：

10.12.7.156 kubernetes-dev-worker-2.com kubernetes-dev-worker-2

最后安装foreman

foreman-installer

需要443端口无占用，会启动443端口

如果执行安装时报错
